Weaving together a hitherto unattempted history of making and verifying identification documents, In Pursuit of Proof tells stories from the ground about the urban margins of India, and Delhi in particular. The book moves with agility across the late colonial era and the postcolonial years marked by ration cards, refugee registration certificates, permits, licences, and affidavits. How did the ration card, introduced during the Second World War, crystallize into proof of residence? After the Partition, how did the Indian state classify refugees as poor, displaced, and lower caste? Might there be alternative conceptualizations of the much-maligned ‘Licence Raj’? How does proof manifest itself for those living in Delhi’s slums? And how does the unique identification number, termed the Aadhaar, impinge on rural migrants dwelling in the city? Relying on intensive ethnographic and archival methods, the book answers these questions and theorizes the Indian state as one whose welfare capacities of governing are drawn from popular knowledge practices of documenting and proving identities.

The story of one of the greatest unsolved problems in mathematics What is the shortest possible route for a traveling salesman seeking to visit each city on a list exactly once and return to his city of origin? It sounds simple enough, yet the traveling salesman problem is one of the most intensely studied puzzles in applied mathematics—and it has defied solution to this day. In this book, William Cook takes readers on a mathematical excursion, picking up the salesman's trail in the 1800s when Irish mathematician W. R. Hamilton first defined the problem, and venturing to the furthest limits of today’s state-of-the-art attempts to solve it. He also explores its many important applications, from genome sequencing and designing computer processors to arranging music and hunting for planets. In Pursuit of the Traveling Salesman travels to the very threshold of our understanding about the nature of complexity, and challenges you yourself to discover the solution to this captivating mathematical problem.

During much of his life Voltaire's plays and verse made him the toast of society, but his barbed wit and commitment to reason also got him into trouble. Jailed twice and eventually banished by the King, he was an outspoken critic of religious intolerance and persecution. His personal life was as colourful as his intellectual one. Voltaire never married, but had long-term affairs with two women: Emilie, who died after giving birth to the child of another lover, and his niece, Marie-Louise, with whom he spent his last twenty-five years. With its tales of illegitimacy, prison, stardom, exile, love affairs and tireless battles against critics, Church and King, Roger Pearson's brilliant biography brings Voltaire vividly to life.
